摘要： PROBLEM TO BE SOLVED: To provide a mud pressure shield method and a mud pressure shield machine capable of executing a tunneling work even for natural ground with many boulders clustered therein in no way inferior to tunneling a general gravel layer.SOLUTION: A mud pressure shield machine 1 has a cutter chamber 5 in a rear of a spoke type rotary cutter 2, which excavates a face Z of natural ground, separated from the same by a bulkhead 4. The mud pressure shield machine 1 has first to third injection means 20 to 22 which inject, toward the face and an inside of the cutter chamber, a chemical which is blended with an excavated soil containing a gravel fraction which is: excavated by a rotary cutter from the natural ground where a sand fraction with a grain diameter less than 2 mm does not exceed 20% and the gravel fraction with the grain diameter equal to or larger than 2 mm exceeds 80%; crushed by the rotary cutter; and brought in the cutter chamber. A mud making material and a cellular material are used in combination for making the chemical so that the same achieves integration between plastic fluidity and impermeability of the soil containing the gravel fraction brought in the cutter chamber as well as the integration between the gravel fraction and the soil.
